Application filed April 5, 1917. Serial No. 160,033.

To all whom t may concern:

` Be itknown'that LsnannZroNr, a `citizen of the United States, residing at 1652 Prospect Place, Brooklyn, in the county of Kings and State of New York, have invented a new and useful Safety Double Boat, of

`which the following is a specification.

The present invention relates to improvements in safety boats, designed especially for saving life at sea, and for providing a sea-worthy boat that will live through high seas, without danger of capsizing. The invention consists essentially in the novel combination and arrangements of parts with a boat of the catamaran or twin-hull type, wherein the propelling and steering apparatus are disposed advantageously between the two hulls, as will be hereinafter more fully described and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of my invention. It will be understood that the two hulls may be spaced wider apart or nearer together, than the distance shown in the drawings, depending upon the surface of the sea upon which the boat is to be used, a turbulent surface requiring that the boats be spaced comparatively far apart, while on a smoother surface the hulls are to be spaced nearer together.

In the accompanying drawings which form a part of my application for patent:

Figure l is a plan view of a boat embodying the novel features of my invention.

Fig. 2 is a stern view of the boat or vessel.

Fig. 3 is a longitudinal sectional view.

In the preferred embodiment of the invention as illustrated in the drawings I have depicted the invention as including the twin hulls 1 and 2, forming a boat of the catamaran type, and constituted of steel plates as shown. Other material, as wood, may of course be used, and preferably the hulls are of thedesign shown in the drawings wherein the beam of each hull is comparatively narrow with relation to the length of the hulls, and the water tight hulls are provided with arched decks 3 and 4 respectively, so that seas shipped may easily be disposed of and the decks kept free of water. The two hulls are connected amidships by a bridge construction or structure 5, which 'spansthe" space "between the'v hulls 'andforms a connection from one deck to the other, as well as forming the foundation for the deck cabin 6. The cabin is of usual or suitable construction, and of course provided with doors and windows and other conveniences, and is designed to inclose the propelling and steering machinery (not shown). A passage is provided fore andaft of the cabin, and protected by the transversely disposed rails 7, 7, in order to permit communication between the decks of the two hulls or boats exterior of the cabin.

The bridge which spans the space between the two hulls forms a rigid connection and brace, but in addition thereto, I utilize transversely disposed rods or beams as 8, 8, toward the bow, and 9, 9 toward the stern of the boat. These rods orbeams are rigidly attached to the hulls and hold the hulls v rigidly spaced apart so that the boat is practically and substantially an integral structure.

At the stern of the boat, and located midway between the two hulls, is an intermediate, watertight, and buoyant compartment l0 designed to support the rudder and propeller and their connections, in the shape of a wedge with its pointed end toward the bow, and with its sides substantially on lines complementary to the curve of the sides of the adjoining hulls. The intermediate structure 10, as seen in Fig. 2, is also provided with tapering sides so that, in cross section the structure is substantially V- shape. This structure is rigidly fixed and held centrally of the'hulls, at the stern of the boat, by the transversely extending beams 11, 11, in the form of rods or bars which, at their Outer ends are firmly secured to the inner sides of the hulls.

The rudder, of usual or suitable type is indicated by the numeral 12, and its steering connections are incased within a pair of tubular structures 13, 13 which extend from the structure 10 to the cabin where the operating parts (not shown) are located.

The propeller 14 is also supported by this structure 10, and the propeller shaft 15 is operated through connections incased in the tubular structure 15 whichalso extends up to lthe cabin, and the connections therein are operated from the motor (not shown) in the cabin.

From the above description taken con nection with my drawings, it is evident that I have provided a safety boat well adapted for rough or turbulent seas, and which may, with facility, be equipped with life saving devices and apparatus of well known types, to render it a highly desirable and efficient v boat of this pattern and for this purpose.

What I claim is Y The combination with the twin hulls and bridge, of transverse beams rigidly connecting the hulls near the bow and stern, a rear, central, buoyant structure V-sliaped longitudinally and vertically and fixed between the hulls, and tubular structures supported between said structure and bridge for incasing the steering connections for the boat.
